BOTTLE GAP OR CLOSURE;

To all whom it may concern:

Be it known that I, WILLIAM H. NIE- -MEYER, a citizen of the UnitedStates, residire; at Baltimore, in the State of Maryland, have inventedcertain new and useful Improvements in Bottle Caps or Closures, of

which the following is a specification.

This invention relatesto im rovements in bottle caps or closures, and te object is to provide a metal cap of the type having'a peripheralflange to be tucked or pressed in under the head of the bottle or jar,so constructed that the flange thereof will readily accommodate itselfto the slight variance in size in the bottle beads .without breaking orsplitting in such a manner as to destroy its effectiveness as a seal.

Vith the above object in view, the invention consists in then'ovelfeatures of construction hereinafter fully described, particularlypointed out in the claims, and

clearly illustrated drawing, in which Figure 1 is a sectional view of acap constructed in accordance with my invention, taken in the'line a:wof Fig. 2 Fig. 2, an elevation of the cap; Fig. 3, a sectional viewonthe line y{i of Fig. 1, nd Fig. 4, asectional View of the cap inposition closing the mouth of the bottle.

Heretofore metal ca s have been provided by the accompanying for sealingbottles, sai caps having continuous flanges, the lower portions of whichare tucked or ressed in under the bead of the bottle. T e beads ofbottles vary slightly in size, that is, in circumference, with the re-'sult that if either smaller or larger than the internal diameter of theflan e of the cap,-

the latter will break or s lit w en pressed in under the former, in suemanner as to pre- -vent a perfect seaL. I obviate th s objeetlon byproviding the flange at intervals about its circumference with thinweb-portions of such slight thickness that the metal at this oint willbreak should the bead be either arger or smaller. The vertical extent ofthis break, however, is limited so that it cannot extend upward asufficient distance to destroy the effectiveness of the seal. Should thebead be smaller, these thin web-portions} Specification of LettersPatent;

by breaking pre ent puckering of the flange by reason of the superfluousmetal and, permitthe separated portions of the flange to be tightlytucked 1n under the bead of the bottle. Y v

Referring now more particularly to the drawing, 1 designates thecaphaving the depending flange 2. f This flange is provided at intervalsabout its circumference with perforations 3, which are placed asuflicient distance below thetop of the cap to prevent anydanger ofinterfering with a perfect seal. E xtending from the lower ed e of theflange, on the inner and outer side t ereof, and terminating at theperforations 3, are substantially V-shaped grooves of such depth as to 7leave a thin wall orweb portion 4. Thus the flange is formed of apluralityof depending portions connected Hy thin web-portions 4..

As shpwn in Fig." 4, the metal cap is so cured upon the bottle bypressin in the flange under the head, at several points about itscircumference, the usual cork disk 5 being placed on the-inside of thecap.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent of theUnited States, is

1. A bottle sealing cap having a top and a continuous flange integraltherewith formed about its circumference with a plurality of spacedperforations and thin web-portions extending from the edge thereof tosaid perforations; A

2. A bottle sealing 'cap having a top and a continuous flange integraltherewith formed at intervals about its circumference with thinWeb-portions extending upward from the edge'the'reof and perforations inwhich said thin portions terminate, said perforations being disposed asuflioient distance below the top of the cap to be below the upper. edgeof the bottle top whenthe cap is in posi tion thereon. l
